ADJUSTABLE AND DE'IIACHABLE GAS BURNER Filed April 21, 1928 PatentedJune 3, 1930 UNITED STATES ATENT OFFICE JOSEPH A. SHITH AND EARL J.HANSEN, OF CLEVELAND, OHIO, ASSIGNORS TO THE CLEVELAND HEATER: COMPANY,OF CLEVELAND, OHIO, A CORPORATION OF OHIO ADJUSTABLE AND DETACHABLE GASBURNER Application filed April 21,

This invention relates to gas burning appliances and in particular theburner assembly and securement means therefor. v

In the assembly andinstallation of water heaters, considerablediflicultyis often encountered in getting the various parts of the heater lined upfor connecting the gas and water pipes. The cause most of the di cultyencountered, particularly where the burner of the heater is connected toa thermostat which is located in the tank of a storage. automatic waterheater.

Water heater bases have been roposed in which the base is adapted to mae. a swivel l6 connection with the heater jacket so that upon looseningof the attachment bolts the heater base may be swung, about its axis.

One of the objects of this invention is to provide in a gas burning apliance having a horizontal Bunsen tube, a justing means whereby theBunsen tube may be positioned to point in any direction of the plane ofits axls.

Another object of this invention is to provide a gas burner assemblythat may be read-. ily'attached or removed from the appliance with whichit is used.

Another object of this invention is to provide a gas burner assemblythat may be readily attached or removed from the appliance with which itis used.

Another object of this invention is to provide an adjustable Bunsen tubethat may be readily and easily locked in the desired position.

Another object of this invention is to provide an improved base andburner assembly that is inexpensive and easily manufactured and whichmay be readily installed on gas 40 burning water heaters.

A further object of' this invention is to provide an improved. burnerassembly that may be used as a replacement unit for water heaters whichwere not originally built with our improved gas burner.

With the above mentioned and other objects in .view, the inventionconsists in the novel construction, arrangement and combination ofparts, hereinafter described, il-

lustrated in some of its embodiments in the as connections usually" 1928Serial No. 271,761.

accompanying drawings and particularly pointed out in the appendedclaims.

One of the advantages of this burner as sembly is that it eliminates agreat deal of expensive pipe fitting in the installation of theappliance, as the Bunsen tube of the burner may be readily swung aboutthe heater base and into alignment with the gas supply pipe. Where ourimproved burner is used in connection with storage automatic waterheaters, it greatly facilitates the assembly of these units as theBunsen tube of. the gas burner can be quickly and easily shifted inorderto line up the gas line 'leading from the tank thermostat.

A further advantage of the above arrangement is that it facilitatestheremoval and replacement of the main burner for cleaning and otherpurposes.

"Referring to the drawings: Fig. 1 is a perspective .view illustrating aside arm gas fired tank heater of the conventional design. Fig. 2 is aplan elevational view of our improved burner base. 'Fig. 3 is a sectiontaken on line 33 Fig. 2. Fig. 4 is a plan elevatlonal view of the Bunsentube locking member. Fig. 5 is a section taken on line 5-5 fig; 4. Fig.6 is a modified form of Bunsen 'The heater shown in Fig. 1 illustratesthe conventional storage water heatin system in which the referencenumeral 1 indicates a storage tank that is adapted to store the airmixing tube 6 in communication with a gas sup 1y line 7. ,The burner 5is adapted to supp y heat to the circulating coils 4 and in this mannerbeat their liquid contents and induce water circulation through thesystem'consisting of the tank 1 and coils 4 and in this manner raise thetemperature of the liquid contents of the tank 1.

In order to facilitate the installation and assembly of the system wehave arranged the Bunsen tube 6 of the heater so that it may be swungabout the heater base and locked in any desired position. The heaterbase 8 is a single casting having a drip pan as an integral part of thebase. The drip pan is provided with a central aperture for the insertionof the upwardly extending portion 10 of the gas and air mixing tube 6.

The Bunsen tube or gas and air mixing tube 6 is provided with a pair'ofoppositely disposed lugs 11 which project from the outer surface of thevertical portion of the tube. An annular ring 16 is provided at thelower portion of the vertical extension 10 to provide an abutment orseating element for the tube.

A lock member 9 having a pair of oppositely disposed wings 14 isprovided for the pur-' pose of locking a Bunsen tube to the burner base8. The locking member 9 has a pair of oppositely disposed slots 12 thatare adapted to register with the lugs 11 and permit the locating of thelocking member below these In S.

In assembling the device the Bunsen tube 6 is inserted in the centralopening of the base 8. The locking member is slipped over the verticalupwardly extending portion of the Bunsen tube with its grooves 1212 inalignment with the lugs 11-11. In this manner the locking member isdropped below the lugs 1111 and it is given a slight twist which bringsthe angular edges 13 into engagement with the lugs 11 and in this mannerclamps the Bunsen tube 6 to the base 8.

It is apparent that by this arrangement the Bunsen tube may be lockedinany desired position. The underside of the locking mem her 9 is providedwith a shoulder 15 for the purpose of centering the device with respectto the central opening 8. i

Fi 6 illustrates a modified form of Bunsen tube in which the lowerportion of the tube is provided with a collar 18 to center the devicewith respect to the base 8.. The base 8 when used in conjunction withthe Bunsen tube 17 I would be cut out at its lower portion in order toaccommodate the collar 18 The above burner locking device could bereadily applied to other gas burning appliances particularly where thereis apt to be difiiculty encountered in assembling the appliance and inmaking the necessary gas connectionsand it is not our intention to limitthis device to a water heater of the type shown which was selected forthe purpose of illustrating one application of our improved burnerassembly.

Furthermore, it is'to be understood that the particular forms ofapparatus shown and described, and the particular procedure set forth,are presented for purposes of explanation and illustration and thatvarious modifications of said apparatus and procedure can be madewithout departing from our invention as defined in the appended claims.

We claim:

1. In a quick detachable burner assembly for water heaters, a waterheater jacket, a

combined base and drip pan rigidly secured to the lower portion of said'acket and having a central aperture formed t erein, a horizontal gasand air mixing tube having a vertically extending portion ada ted toproject in the central opening of said base, lugs formed on thevertically extending mixing tube, a locking mem or adapted to engagesaid lugs to lock said mixing tube in di erent positions on said base,and a removable burner head adapted forv reception on said verticalportion of said mixing tube.

2. In a structure of the class described, the combination of anapertured base member and a horizontally disposed mixing tube having avertically extending portion adapted to be freely received in theaperture of said base member, and means cooperating with theverticallyextending portion of said mixing tube and said base memberproviding a swivel connection and lock for said tube with said basemember.

3.

4. In a structure of the class described, the combination of anapertured base member, and a horizontally disposed mixing tube having avertically extending portion adapt ed to be freely received in theaperture of said base member, lugs' formed on the vertically extendingportion of said tube, and means engaging said lugs and base memberproviding a swivel connection and lock for said tube with said basemember.

5. In a structure of the class described, the combination of anapertured base member, and a horizontally disposed mixing tube having avertically extending portion adapted to be freely received'in theaperture of said base member, lugs formed on the vertically extendingportion of said tube, and a slotted wing nut having helical surfacesadapted to engage said lugs to adjustably secure said tube to said basemember.

6. A base member, a short cylindrical wall provided by said memberdefining an aperture therethrough, a circumferentially adjustable sideoutlet mixing tube adapted to be loosely received in the aperture ofsaid base member,
